
The do file to use in order to obtain a labour pooling proxy is:

"Labour_pooling_9599_RESTAT.do" (Stata do file)

This do file uses Labour Force Survey (LFS) data between 1995 and 1999 to construct the labour pooling measure used by Ellison-Glaeser-Kerr, 2010.
See our manuscript for details and references. This metric measures the correlation of different types of occupations used in industry pairs.

The LFS can be accessed by authorised users via the UK Data Service Secure Lab. The LFS data stored on the Secure Lab have detailed geographical identifiers (wards)
These allow mapping individuals to Travel to Work Areas. This detail cannot be obtained outside the Secure Lab.

The do file also uses standard intermediate do files that in-sheet and keep variables from LFS data files (various quarters and years).
These are also available for Secure Lab users.

The main do file constructs this labour pooling measure for the period 1995-1999. The output file is called:

-lab_pool9599.dta

An alternative time window covering the period 1994-2000 was also used in some robustness checks. 
This can be obtained by altering some of the loops and restrictions in this main do file.
